Moving the tests over to CircleCI in pretty much "as-is" state just so that we can drop the dependency on Travis. In the followup changes we plan to migrate these tests to run on sauce under bazel. @gregmagolan is working on that. I've previously verified that all the tests executed in legacy-unit-tests-local already under bazel. Therefore the legacy-unit-tests-local job is strictly not necessary any more, but given how flaky legacy-unit-tests-saucelabs is, it is good to have the -local job just so that we can quickly determine if any failure is a flake or legit issue (the bazel version of these tests could theoretically run in a slightly different way and fail or not fail in a different way, so having -lcoal job is just an extra safety check). This change was coauthored with @devversion PR Close #27937
Encryption
Based on https://github.com/circleci/encrypted-files
In the CircleCI web UI, we have a secret variable called KEY
https://circleci.com/gh/angular/angular/edit#env-vars
which is only exposed to non-fork builds
(see "Pass secrets to builds from forked pull requests" under
https://circleci.com/gh/angular/angular/edit#advanced-settings)
We use this as a symmetric AES encryption key to encrypt tokens like a GitHub token that enables publishing snapshots.
To create the github_token file, we take this approach:
- Find the angular-builds:token in http://valentine
- Go inside the CircleCI default docker image so you use the same version of openssl as we will at runtime:
docker run --rm -it circleci/node:10.12 - echo "https://[token]:@github.com" > credentials
- openssl aes-256-cbc -e -in credentials -out .circleci/github_token -k $KEY
- If needed, base64-encode the result so you can copy-paste it out of docker:
base64 github_token
